BitmapImage-> SetSource不更新Binding [英] BitmapImage->SetSource doesn't update Binding

问题描述

我有一个带有自定义ItemTemplate的ListView。在模板中，我有带有绑定的Image对象：
$
< Image Source =" {Binding AlbumArt}"余量= QUOT; 0" Stretch =" Uniform" />

接下来在app中我将ItemsSource设置为Object ^的向量^：

ctrlListView- > ItemsSource = m_items; （m_items是IVector< Object ^> ^）

在这个向量中我有我的TItem对象 其中我还有BitmapImage和任何其他字段（String ^）。当项目已经在m_items中（并且在ListView中可见）时，更新到BitmapImage不会更新ListView。如果
我会更改数据中的任何内容（它不会自动生效），我如何刷新ListView？

I have a ListView with custom ItemTemplate. In the template i have Image object with Binding :
<Image Source="{Binding AlbumArt}" Margin="0" Stretch="Uniform"/>

Next in app i set ItemsSource to vector of Object^:
ctrlListView->ItemsSource = m_items; (m_items is IVector<Object^>^ )

In this vector i have my TItem objects where i have also BitmapImage and any other fields (String^). When items are already in m_items (and visible in ListView), then update to BitmapImage doesn't update ListView. How can i make ListView refreshed when i'll change anything in data (it does not work automatically) ?
